Do you remember when Jim Carrey used to be funny? I mean, he used to be really, really funny, didn't he?

I can't tell if he's the one who's changed or if I'm just old and curmudgeonly now, but every time I see him doing his patented Jim Carrey Shtick, it makes me cringe. I saw him on David Letterman a few weeks ago, and Carrey had this painfully lame bit where he kept referencing his entourage of hookers and the camera would flash backstage to a trio of elderly women who were hooking a rug.

GET IT? THEY WERE HOOKING A RUG WHICH MAKES THEM HOOKERS NOT PROSTITUTES HA HA HA ugggggh.

In the searingly clever (not) parody of Darren Aronofsky's thriller, Carrey took on Mila Kunis' character, Lily, the rival to Natalie Portman's Nina. He wore a bun, black leotard, buffalo wings tattooed on his back, and tutu (ha ha ha A MAN IN A TUTU HAAA uggggh), and pranced around the stage contorting his face into various rubbery positions.

At the end, Carrey addressed the audience and delivered the flaccid line, "Once you go black swan, you never go back ... swan," before the sketch faded to an image of Carrey in full Swan Lake makeup.

It all left me with one burning question—Dumb and Dumber really was funny, wasn't it? I could swear it was funny.
